High blood pressure (hypertension) happens when your blood has a hard time getting through the body, usually because of narrowed arteries. Nitroglycerin is a vasodilator. This means it widens the arteries so your blood can more freely move through them, your heart does not have to work so hard, and this lowers your blood pressure.
